Title: Process for the purification of cycloalkanone  mixtures obtained in the oxidation of cycloalkanes
Inventor: PLANTEMA OTTO G
IPC: C07C45/00
Filed: 1979-07-25
Granted: 1982-05-11
Abstract: ABSTRACT OF THE DISCLOSURE           Aldehydes are removed by aldol condensation from a mixture containing a C5-C12 ring atom cycloalkanone, aldehydes and corresponding cycloalkyl esters of C4 or greater carboxylic acids, the mix-ture resulting from the liquid phase oxidation of the corresponding cycloalkane with molecular oxygen.  The aldol condensation reaction converts at least 80% of the aldehydes present while no more than 20% of the cycloalkyl esters are saponified.  A slight excess of no more than 2% of the cycloalkanone required for the aldehyde removal is converted in the aldol condensa-tion.  Cycloalkanones thus treated and freed of the aldehyde are processed into polylactams exhibiting particularly high mechanical strengths.

Abstract: ELECTRONICALLY CONTROLLED DIESEL UNIT INJECTOR                ABSTRACT    A fuel injector (10) is provided for each cylinder of an internal combustion engine, the injector including an electronically  operated  control  valve  (146)  disposed between supply passage 42 and a timing chamber  (98)  to control the admission of fuel into and out of the timing chamber. A primary pumping plunger (62) and a secondary plunger (90) are axially spaced within the central bore of the injection body, and a normally closed injection nozzle (14)  is situated at one end of the injector body.   A mechanical linkage (27, 28, 30) associated with the cam-shaft of the engine drives the primary pumping plunger (62) against the bias of a main spring (18).  The timing chamber [98) is defined between the plungers (62, 90) and a metering chamber (128) is defined between the secondary plunger (90) and the nozzle (14).     An electronic control unit (52) responds to engine operating conditions, and delivers a timing and metering signal to the control valve (146) to close the valve and seal the timing chamber for a controlled period of time. The sealed timing chamber forms a hydraulic link, so that the plungers (62, 90) move in concert during the injection and metering phases of the cycle of operation.  When the signal from the ECU is  terminated,  the control  valve opens, and breaks the link so that the primary plunger (62) moves independently of the secondary plunger  (90) which is biased in a set position by a spring (96) after termination of the control signal.    The timing function can be adjusted by the ECU rela-tive to any preselected position of the crankshaft to optimize engine performance, while the metering function is achieved in a proportionate manner relative to the degree of camshaft rotation.  A cam (22), having a linear portion, controls the mechanical linkage, and thus the primary pumping plunger (62), to produce the proportional metering function.

Abstract: Abstract of Disclosure A liquid crystal temperature indicator measures human body temperatures.  The temperature indicator comprises a generally planar member for retention against an outer surface of a body.  A number of deposits of liquid crystals, each activatable within a predetermined temperature range to be measured, are arranged behind temperature-indicating numerals.          At a temperature within the predetermined temperature range, at least one of the deposits emits or reflects visible radiation to make corresponding numerals visible for indicating the surface temperature of the body.  However, numerals are calibrated to the corresponding oral temperatures.  A non-water soluble lacquer coating protects the deposits from moisture or humidity.

Abstract: Case 2701 IMPROVED MOTOR SWITCH              ABSTRACT OF THE DISCLOSURE This invention relates to an improved switch which is mounted on the end shield of a dynamoelectric machine within the radial periphery of the machine.  The improved switch includes an actuating mechanism which is operable to disengage a starting circuit of the machine and engage a load simultaneously by acting against switch blade members mounted within the casing of the switch.  The actuating mechanism includes first and second actuating members longitudinally extending radially of the machine and a U-shaped leaf spring longitudinally extending perpendicular to the first and second actuating members across the end shield.  The present invention is an improvement over the prior art which provided a coiled spring extending radially of the machine.  The present invention, by providing a leaf spring extending perpen-dicularly of the actuating members, reduces the special requirement of the spring mechanism by at least 50% over that of the prior art and as a result ensures that the switch does not protrude beyond the periphery of the motor.
